Brand Loyalty In The Automotive Community: A Case Study On The Chevrolet Corvette, Michele Ann Motichka

USF Tampa Graduate Theses and Dissertations

This is a qualitative case study conducted to investigate the relationship between consumers who are brand loyal to a certain product and the groups that are formed to bring these enthusiasts together, using the Chevrolet Corvette and its community as a model. Qualitative research lends itself to studying relationships and social situations, in being able to observe and participate in a social context, rather than analyzing it from the outside looking in. By approaching this subject as a case study, an element of flexibility was allowed. This study primarily focuses on one main phenomena, the social groups formed by loyal …

A Comparison Of Meta-Analytic Approaches To The Analysis Of Reliability Estimates, Denise Corinne Mason

USF Tampa Graduate Theses and Dissertations

In the last few years, several studies have attempted to meta-analyze reliability estimates. The initial study, to outline a methodology for meta-analyzing reliability coefficients, was published by Vacha-Haase in 1998. Vacha-Haase used a very basic meta-analytic model to find a mean effect size (reliability) across studies. There are two main reasons for meta-analyzing reliability coefficients. First, recent research has shown that many studies fail to report the appropriate reliability for the measure and population of the actual study (Vacha-Haase, Ness, Nilsson and Reetz, 1999; Whittington, 1998; Yin and Fan, 2000). Second, very little research has been published describing the way …

Representation And Interpretation Of Manual And Non-Manual Information For Automated American Sign Language Recognition, Ayush S. Parashar

USF Tampa Graduate Theses and Dissertations

Continuous recognition of sign language has many practical applications and it can help to improve the quality of life of deaf persons by facilitating their interaction with hearing populace in public situations. This has led to some research in automated continuous American Sign Language recognition. But most work in continuous ASL recognition has only used top-down Hidden Markov Model (HMM) based approaches for recognition. There is no work on using facial information, which is considered to be fairly important. In this thesis, we explore bottom-up approach based on the use of Relational Distributions and Space of Probability Functions (SoPF) for …

Design And Characterization Of Multi-Layer Coplanar Waveguid Baluns And Inductors, Khaled Obeidat

USF Tampa Graduate Theses and Dissertations

This work examined the design and characterization of multilayer coplanar waveguide baluns and inductors. This work derives a design procedure that helps RF engineers design cost effective multilayer coplanar waveguide (CPW) spiral balun that works in the frequency range 1-8 GHz. The accuracy of the developed procedure has been proven by designing two balun circuits of different dimensions and simulating them using available commercial software, Momentum (MoM) and Empire (FDTD). The simulation results have shown good balun performance over the desired frequency range. Furthermore some of the designed balun circuits have been fabricated and measured and the results agree with …

Direct 3d Interaction Using A 2d Locator Device, Anees Ansari

USF Tampa Graduate Theses and Dissertations

Traditionally direct 3D interaction has always been limited to true 3D devices whereas 2D devices have always been used to achieve indirect 3D interaction. Till date no proper research has been done to try and extend the use of mouse to direct 3D interaction. In this research we explore the issues involved with using the mouse to accommodate the additional degrees of freedom required for 3D interaction. We put forth a unique and innovative design to achieve this objective and show that even a device as simple as the mouse can be highly effective for 3D interaction when supported by …

On The Indemonstrability Of The Principle Of Contradiction, Elisabeta Sarca

USF Tampa Graduate Theses and Dissertations

In this thesis I examine three models of justification for the epistemic authority of the principle of contradiction. Aristotle has deemed the principle "that the same attribute cannot at the same time belong and not belong to the same subject and in the same respect" the most certain and most prior of all principles, both in the order of nature and in the order of knowledge, and as such it is indemonstrable. The principle of contradiction is involved in any act of rational discourse, and to deny it would be to reduce ourselves to a vegetative state, being incapable of …

Flat Chests And Crossed Eyes: Scrutinizing Minor Bodily Stigmas Through The Lens Of Cosmetic Surgery, Joan Ann George

USF Tampa Graduate Theses and Dissertations

If cosmetic surgery has become the cultural lens through which Americans look at issues of beauty and ugliness (Haiken 1997), then minor bodily stigma is the personal lens through which we scrutinize our bodies and self-diagnose our own flaws in the first place (Ellis 1998). In this dissertation, I interrogated the stories of eight women who struggled with two specific minor bodily stigmas--strabismus (crossed eyes) and micromastia (small breasts). Cosmetic surgery presents a potential "cure" for both of these conditions, however, as some of my interviewees could testify, the results are unpredictable. While some women reported being grateful that they …

Validity Generalization And Transportability: An Investigation Of Distributional Assumptions Of Random-Effects Meta-Analytic Methods, Jennifer L. Kisamore

USF Tampa Graduate Theses and Dissertations

Validity generalization work over the past 25 years has called into question the veracity of the assumption that validity is situationally specific. Recent theoretical and methodological work has suggested that validity coefficients may be transportable even if true validity is not a constant. Most transportability work is based on the assumption that the distribution of rho ( ρ_i ) is normal, yet, no empirical evidence exists to support this assumption. The present study used a competing model approach in which a new procedure for assessing transportability was compared with two more commonly used methods. Empirical Bayes estimation (Brannick, 2001; …

Estimates Of Statistical Power And Accuracy For Latent Trajectory Class Enumeration In The Growth Mixture Model, Eric C. Brown

USF Tampa Graduate Theses and Dissertations

This study employed Monte Carlo simulation to investigate the ability of the growth mixture model (GMM) to correctly identify models based on a "true" two-class pseudo-population from alternative models consisting of "false" one- and three-latent trajectory classes. This ability was assessed in terms of statistical power, defined as the proportion of replications that correctly identified the two-class model as having optimal fit to the data compared to the one-class model, and accuracy, which was defined as the proportion of replications that correctly identified the two-class model over both one- and three-class models. Estimates of power and accuracy were …

Computer Mediated Peer Response And Its Impact On Revision In The College Spanish Classroom: A Case Study, Ruth Roux-Rodriguez

USF Tampa Graduate Theses and Dissertations

Peer response in which students work together in dyads or small groups to critique and provide feedback on one another's writing is compatible with communicative approaches to foreign language teaching and process approaches to the teaching of writing. Computer-mediated communication has been considered a viable tool for both the teaching of languages and the teaching of writing. There is, however, scant information on how computer-mediated peer response functions in the foreign language classroom. This dissertation investigated how college Spanish learners provided feedback to their peers and the impact of feedback on revision. It also examined the factors that influenced how …

Construction Of Smoking-Relevant Risk Perceptions Among College Students: The Influence Of Need For Cognition And Message Content, Jennifer Elaine Irvin

USF Tampa Graduate Theses and Dissertations

The primary purpose of this study was to examine the potential joint influence of need for cognition (NC), the dispositional preference for engaging in (or avoiding) effortful cognitive processing of information, and type of smoking risk message (i.e., factual and evaluative messages similar in message content and length) on the construction of smoking-relevant risk perceptions among college smokers. A secondary purpose was to examine potential mechanisms through which changes in risk perception might occur. 227 college smokers evaluated one of three pamphlets, (1) a factual (i.e., primarily fact-based) smoking risk pamphlet, (2) an evaluative (i.e., primarily emotion based) smoking risk …

Fourier-Transform Infrared Spectroscopic Imaging Of Prostate Histopathology, Daniel Celestino Fernandez

USF Tampa Graduate Theses and Dissertations

Vibrational spectroscopic imaging techniques have emerged as powerful methods of obtaining sensitive spatially resolved molecular information from microscopic samples. The data obtained from such techniques reflect the intrinsic molecular chemistry of the sample and in particular yield a wealth of information regarding functional groups which comprise the majority of important molecules found in cells and tissue. These spectroscopic imaging techniques also have the advantage of acquisition of large numbers of spectral measurements which allow statistical analysis of spectral features which are characteristic of the normal histological state as well as different pathologic disease states. Databases of large numbers of samples …

An Indepth Analysis Of Face Recognition Algorithms Using Affine Approximations, Lakshmi Reguna

USF Tampa Graduate Theses and Dissertations

In order to foster the maturity of face recognition analysis as a science, a well implemented baseline algorithm and good performance metrics are highly essential to benchmark progress. In the past, face recognition algorithms based on Principal Components Analysis(PCA) have often been used as a baseline algorithm. The objective of this thesis is to develop a strategy to estimate the best affine transformation, which when applied to the eigen space of the PCA face recognition algorithm can approximate the results of any given face recognition algorithm. The affine approximation strategy outputs an optimal affine transform that approximates the similarity matrix …

Failure Of The Russian Democratic Reforms: The Democratization Of The Big Bear, Nicolé M. Hicks

USF Tampa Graduate Theses and Dissertations

Looking back at the past twelve years, many would say that it appears Russia has lost the battle for liberal democratic reform. Among Russia watchers, the following question has been circulated: "Who lost Russia?" This debate has polarized most scholars into one of two camps: those who feel the reforms failed (the critics) and those who feel the reforms were a success (the supporters).

This paper will explain why the Russian reforms failed. By filling in the holes left by current research, the author will demonstrate that the truth may lie somewhere in between the two opposing sides.

Hearing Evaluation In Infants: An Update For Pediatricians, Janet E. Sullivan

USF Tampa Graduate Theses and Dissertations

This paper provides an overview of developmental timetables relevant to hearing and of current pediatric audiological techniques and practices. The first sections summarize structural and functional development of the auditory pathway and the development of primary auditory processing. These developmental sequences appear to follow similar paths in humans and animals. Speech and music perception involve more complex processing and are strongly influenced by experience. Hearing disorders affect the perception of complex sounds in a variety of ways, depending on the site(s) of lesions. Early onset hearing impairment, including conductive loss from chronic otitis media, can seriously impede language development.

A Qualitative Analysis Of Trust Issues In The Journalist/Government Communicator Relationship: An Exploratory Study, Davina Yetter Gould

USF Tampa Graduate Theses and Dissertations

At a glance, journalists and public relations practitioners appear to have a dysfunctional relationship, despite having many professional similarities. Both groups use comparable skill sets in their jobs, including writing, information gathering, and making decisions based on news values. Both groups often work with each other in their professional positions; journalists look to public relations practitioners for sources and news tips, while public relations practitioners look to journalists to help send organizational messages to publics.

To better understand the issues of trust in this unique working relationship, ten journalists and ten government public information officers from the Tampa Bay, Florida …

An Analysis Of Workplace Amputation Injuries In Florida, Eve N. Hanna M.D.

USF Tampa Graduate Theses and Dissertations

Nationally, 10,852 workplace amputation injuries in the US were reported in 1997. This number has been gradually decreasing over time to 9,658 amputations in 2000. In Florida, the amputation injuries have been increasing from 272 in 1997 to 417 in 2000. The reason for this increase is unclear and deserves further study. The purpose of a portion of this study was to examine the Federal and Florida BLS data to determine the characteristics of the typical worker with an amputation injury.

Population Structure Of The Gopher Tortise (Gopherus Polyphemus) In Florida, Using Microsatellites, Tonia S. Schwartz

USF Tampa Graduate Theses and Dissertations

Gopher tortoise (Gopherus polyphemus) population sizes have drastically declined in the past 100 years. Much of this decline has been attributed to past human predation, to habitat loss from human development, and potentially to the recently discovered upper respiratory tract disease. An understanding of the genetic structure among populations is critical for the long-term success of relocation and other management strategies. This research focuses on the development of a suite of genetic markers and the answers they provided to questions concerning present day population genetics and its use in management. In addition, this study provides inference on historical …

Modeling Dynamic Interactions In A Software Development Project, Chetan D. Vajre

USF Tampa Graduate Theses and Dissertations

Software industry is getting very competitive in the wake of recession. In most cases, an organization that quotes a lower price and promises to deliver the product at the earliest walks away with the project. But the factor of quality of the product delivered is also very important because that in turn determines the reputation of an organization, which also plays an important role in getting the next project.

Interactions in a software development are dynamic in nature and involve human factors. Models are built taking into account all possible factors so as to present a realistic picture of the …

The Effect Of Digital Technology On Late 20th Century And Early 21st Century Culture, Jennifer Clarke

USF Tampa Graduate Theses and Dissertations

Recently, artists have begun using digital technology to create new cultural forms in the fields of art, literature, and music, and a new cultural form known as interactive digital multimedia has emerged, which combines elements from the new artistic, literary, and musical forms. Many of these artists have produced works that explore the interactive capabilities of digital technology. These interactive digital cultural forms have encouraged collaborative efforts that would have otherwise been difficult or even impossible to achieve before the advent of digital technology. In addition, this element of interactivity has redefined the traditional relationship between artist and audience. As …

Alexander Pope's Opus Magnum As Palladian Monument, Cassandra C. Pauley

USF Tampa Graduate Theses and Dissertations

The overarching goal of this study is to suggest that Alexander Pope did not abandon his project for a "system of ethics in the Horatian way," but rather that in his final days he did find a way to unite the parts at hand into a viable whole. Constructing such an argument, however, requires a similar building up from the parts, and so the core focus becomes a study on the way the image of an arch can serve as a metaphor for Pope's reconciliation scheme in his Moral Essays as he "steers betwixt" seeming opposites.

To justify this approach, …
